摘要： The specification describes multimode optical fibers produced by improved methods that reduce the manufacturing cost. These methods may also be more efficient in terms of power loss. In one of the embodiments, the improved design has a large core of pure silica derived from a rod-in-tube method. In the embodiment, a down-doped cladding is produced by depositing fluorine-doped silica on the inside of a silica starting tube using isothermal radio frequency plasma deposition. The silica core is inserted and the starting tube collapsed. The silica starting tube is removed and optical fiber is drawn from the fluorine-doped glass coated silica rod.
